Specification of Letters Patent.

Patented June 22, 1915..

To (ZZZ whom it may concern:

Be it known that I, BLAIR l-IAnons'rY, a citizen of the United States, residing at Clifton Forge, Virginia, have invented a certain new and useful Improvement in lVork- Guides for Sewing-Machines, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a top plan view. Fig. 2 is a side elevational view. Fig. 3 is a fragmentary enlarged top plan View.

This invention relates to a new and useful improvement in sewing machines designed especially for sewing leather, and particularly to that class shown in the patent to Pedersen, No. 811,582, dated February 6, 1906.

This present invention is directed particularly to a novel means for adjustably holding or guiding the work while it is being fed through the machine, said means being adjustable during the time that the machine is operated, thus enabling the operator to quickly and easily regulate the machine for different kinds of work without necessitating the stopping of the machine. I have not shown the stitch forming mechanism in the accompanying drawings, as the same forms no part of my invention, and with respect to the awl operating and feeding mechanism, attention is directed to the Blair Patent, No. 1,092,892, dated April 1 1, 1914, which is herein illustrated.

In the accompanying drawings, 1 indicates a portion of the frame of the machine which is provided with a forwardly eX- tending portion 2 constituting a work table in which the slot 3 is arranged for the awl 4. I deem it unnecessary to describe the operation of this awl feeding and operating mechanism, as the same is fully set forth in the Blair patent before mentioned. Heretofore this work table has been provided with a threaded opening for the reception of a machine screw or bolt carrying a roller or post adjacent the awl slot, and which post constituted a work guide. Posts of different diameters were used for work of different kinds, but it is obvious that when it was desired to change a post of one size for a post of a different size, that the one in position had to be removed and the other substituted therefor.

lit is the purpose of my present invention to obviate the necessity for removing or subst1tuting one piece for another, and hence l. arrange on the work. table a guiding post 5 with which coiiperatcs the slotted end of a work guiding member 6, the slot in said work guiding member being inclined to its direction of movement. This work guiding member is preferablv in the form of a link whose opposite end is pivotally connected to a crank pin 7 arranged on a notched disk 8. Thenotches of this disk cooper te with a detent or restraining spring 9, there being a handle 10 connected to the shaft of the disk by which same may be rotated.

As shown in F 1, the work guide is adjusted to its position closest to the awl, but by rotating the disk through the medium of the handle in an anti-clockwise direction, the work guide will be moved away from the awl, the adjustment continuing to the position shown in full lines in Fig. 3. Of course it is understood that this range of ad justment can be increased or diminished as necessity requires, and also that the operating face of the work guide, here shown as beveled, can be modified to suit the character of work to be done on the machine.

What 1 claim is:

1. A work guide for sewing machines comprising a work table, a work guiding member having a slot and pin connection with the table, said slot being at an angle to the line of movement of the member, an actuating member connected for operating the guiding member, and means yieldably engaging the actuating member to hold the guiding member in adjusted positions.

2. A. work guide for sewing machines comprising a work table, a work guiding member disposed obliquely to the line of travel of the work and having movable con nection with the table, an actuating member connected for operating the guiding member, and means yieldably engaging the actuating member to hold the guiding member in adjusted positions.

3. A work guide for sewing machines comprising a work table and a work guiding member mounted hereon by a slot and pin connection, said slot being arranged at an angle to the direction of movement of said work guiding member, means for moving having a slot and pin connection with the table, said slot being disposed at an angle to the direction of movement of the member, a

hand lever connected for rotating the disk to adjust the guiding member, and a spring detent cooperating with said teeth for bolding the member in adjusted positions.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses, this 27th day of October, 1914c.

BLAIR HARDESTY.
